the proposed fix does not work for me. That is, I tried installing Microsoft's xaudio implementation but the problem persists after doing this
Oops, I forgot to set an override xaudio2_7 in winecfg to make Wine use the native Windows library. All sound *does* work in wine-staging 3.5-1 if the override is set (and xact is installed via winetricks).
